u call them centimeters.
They are called millimeter lines.
To show 15 mm on a ruler, locate the millimeter markings, which are typically the smaller lines between the larger centimeter markings. Count 15 small lines from the 0 mark, as each small line represents 1 mm. The 15 mm mark will be exactly at the 15 mm line, which is also 1.5 cm on the ruler. Make sure to use a ruler that includes millimeter measurements for accurate representation.

A 16-mark looks like a small vertical line that is slightly longer than the surrounding lines on a standard ruler. It typically falls between the 15-mark and the 17-mark on the ruler scale.
If the lines are on the opposite side of the inches on the ruler, then yes. You must keep in mind, however, that a ruler is used for inches and that the centimeters may not be marked.

To create an easy drawing of a ruler, start by drawing a straight line for the ruler's body. Add small lines perpendicular to the body to represent the measurement marks. Label the marks with numbers to indicate the measurements. Finally, add a small rectangle at one end to represent the handle of the ruler.
